For those of you for whom the 2-minute digest would suffice, here it is, while I download the 1-hour version.
Again, the balloon flying operation to peek at the operation floor (5th floor) of Reactor 1 at Fukushima I Nuke Plant had failed once in August, and on October 24, Hitachi and TEPCO workers managed to fly a modified balloon to get past an obstacle that had foiled their previous attempt.
I still wish they did the untethered drones instead, so that we get to see parts not close to the shaft in more details.
When a hydrogen explosion happened in the Reactor 1 building on March 12, 2011, the wall panels of the operation floor of Reactor 1 blew out (as they should), and the ceiling collapsed (as it shouldn't).
Here's the digest version, from TEPCO's Photos and Videos (10/25/2012):
Full-length (to be uploaded):
(2/2, very short, the balloon starts to descend)
**CAUTION** to those of you who are downloading from TEPCO's Photos and Videos page:
Starting sometime in early October, TEPCO restricts the time period to make any full version of the videos that they take to only one week. The longer version of this balloon video, which I'm downloading right now, is available only up to November 1st. I already missed downloading the video of the Reactor 1 Containment Vessel probe video.
Some transparency and openness after the takeover by the national government.
